The dynamics of barley grain germination represented by calculated Percentage of Germination (%) on 1st, 2nd, 3rd, 4th and 5th day of cultivation. Variants: C—control/untreated barley grains; O10–O300: barley grains treated with plasma generated in an oxygen atmosphere for 10, 20, 30, 60, 180 or 300 s; A10–A300: barley grains treated with plasma generated in ambient air for 10, 20, 30, 60, 180 or 300 s; N10–N300 barley grains treated with plasma generated in a nitrogen atmosphere for 10, 20, 30, 60, 180 or 300 s. Bars are means of ten experimental runs (one run represents 50 grains per variant, n = 500) ± SD.
